Sima Guang's Paradise reading room alone has 10,000 redundant books on literature and history. Among them, the book that Sima Guang often reads every morning, although read for decades, looks as new as if he had never touched it with his hands. Sima Guang once said to his son during the public holiday: "Businessmen love to collect money, while Confucianism only collects these (books), so we should know how to cherish them. Every year when the weather is fine, I will set up several book cases on sunny days, put those books on them obliquely and cross the sewing thread. So although it took a long time, the book was not damaged. When it comes to opening books, you must first tidy up a few cases, put a mattress under the book, and then sit up and read. Sometimes (you can't sit up and read) you need to read while walking, so you should put the book on the square (read) and never dare to hold the book directly with your hands. This is not only worrying that your hands will sweat on the page, but also worrying that you will touch the thread of the book. After reading each page, stick the thumb side of your right hand on the edge of the page, and then twist the page with your index finger (matched with your thumb) so that you can turn over a page, so that you can not destroy the paper. I often see you pick up the pages directly with your fingers when turning pages, which is quite different from what I mean. Now people in Buddhism and Taoism (monks and Taoists) still know how to respect their scriptures. How can we Confucianism be worse than them? You must remember my words. " Please accept the answer!
